DIPPING APPARATUS FOR HAT-FORMING MACHINES.

SPECIFICATION forming part of Letters Patent No. 425,901, dated April15, 1890.

Application filed October 4, 1888. Renewed February 12, 1890. Serial110,340,154. (No model.) V

To @ZZ whom it may concern:

Be it known that l, SEYMOUR C. PALMER, a citizen of the United States,residing at South Norwalk, in the county of Fairfield and State ofConnecticut, have invented cert-ain new and useful Improvements inDipping Apparatus for Hat-'Forming Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and luse the same.

My invention relates to certain improvements in hat-forming machineswith the end in view to facilitate the operation of dipping the hat-bodyin Water; and it consists in the details of construction and combinationof elements, such as will be hereinafter fully set forth, and thenspeciiically designated bythe claim.

In the accompanying drawings, Figure 1 is a side elevation of myimprovement, and Fig. 2 a front elevation, the plunger-rod being brokenaway. v

Similar letters denote like parts in both figures.

In my pending application, filed in the United States Patent Office onthe Qatnday of September, 1888, under Serial No. 286,147, I showed anddescribed a hat-dipping apparatus in which the structure and operationof the hat-supporting means and the mechanism for operating to lower andelevate the rod P are precisely the same as in the instance of thepresent improvement, and I therefore will enter into no detaileddescription of this means or mechanism, as they form no part of thepresent invention.

A is the tub containing water within which the hat-body A is to bedipped, and B are guide-lugs projecting from said tub.

C is the platform on which the cene is placed, and D is a bail securedat the ends to the platform and guided through the lugs B.

E E are hangers; F, a counter-shaft journaled within said hangers; G,-apulley loose on said shaft and having a hub H, within whichv latter areformed notches a; I, a disk rigid on said shaft; J, a bolt 'extendingloosely through said disk and rendered resilient by the action of aspring b, secured to said disk; K, an arm secured to the hanger E', andL is a detent pivoted to said arm and sustained in elevation by acoil-spring o, attached at its extremities to said arm and detent. Thenose of said detent is beveled, as seen at d, and is within the iield oftravel of the heel end of the bolt J, so that when said heel end iscarried against the beveled nose the bolt will be withdrawn against theresiliency 0f the spring b, and the said heel will be arrested by thestop-lug e at the base of the beveled nose.

All the parts hereinbefore setV forth are the same with respect toconstruction and operav y tion as are the similar parts shown anddescribed in my aforesaid pending application.

M is a face-cam rigidly mounted on the shaft F.

N is a lever pivoted at the rear end to the hanger O, and P is a rigidrod pivoted at its extremities to the forward end of the leverN and tothe top of the bail, respectively.

Q is the camgroove within the face-cam, and Within this groove extends apin R, which projects laterally from the lever N, so that it will beseen that motion is communicated to the rod P from the cam-groove Qthrough the intermediate lever N. The contour and extent of thecam-groove are such with respect to the shaft F that a verticalreciprocation of variable speed will be imparted to the lever N and rodP, whereby the hat-body A on its cone will be properly dipped.

'In my aforesaid pending application the operation of the crank-pinwithin the slotted lever rendered the construction therein shown capableonly of a limited variable motion, for the reason that during thefastest and slowest movements of the lever the crank-pin traveled inopposite directions within the same section of the slot, thusnecessarily limiting the fastest movement by the slowest, and viceversa. The present improvement obviates this disadvantage and greatlyincreases the capability of the apparatus, since the cam-groove istraversed but once by the pin R, and accordingly there is no limit tothe degree of variation of said groove, and the Very finest hats may betary shaft, and the pin extending from said ro dipped Within a, giventime and at any delever Within the groove 0f said cam, substansiredvarying speed. tially as set forth.

Having thus described my invention, Whatl In testimony whereof I aix mysignature 5 claim as new, and desire to secure byLetters in presence oftwo Witnesses.

Patent, is SEYMOUR C. PALMER. The combination of the pivoted lever, theWitnesses: hat-supporting mechanism suspended there- S. S. WILLIAMSON,
